          Abstract

          La realización de una sesión de hemodiálisis (HD) supone un cierto riesgo de aparición de reacciones adversas de hipersensibilidad, al estar en contacto abundantes cantidades de sangre con diferentes materiales de origen sintético. En HD han sido descritas reacciones de hipersensibilidad al óxido de etileno y a membranas no biocompatibles como el cuproamonio. También se han comunicado casos de hipersensibilidad con membranas biocompatibles como la polisulfona, e incluso con polisulfona asociada a polivinilpirrolidona. En este artículo queremos describir seis casos acontecidos en nuestro servicio de reacciones de hipersensibilidad mayoritariamente temprana a la sesión de HD, caracterizados por mal estado general, desaturación, broncoespasmo e hipotensión arterial, con buena respuesta a la suspensión temporal de la sesión y con reaparición en sesiones posteriores siempre que se utilizase un dializador sintético. Todas tienen en común no haberse dado de nuevo en sucesivas observaciones cuando las sesiones fueron realizadas con una membrana de celulosa.

          Undergoing a haemodialysis (HD) session poses a certain risk of hypersensitivity adverse reactions as large quantities of blood are in contact with various synthetic materials. Hypersensitivity reactions to ethylene oxide and non-biocompatible membranes, such as cuprophane, have been described in HD. Cases of hypersensitivity with biocompatible membranes, such as polysulfone, and even polysulfone-polyvinylpyrrolidone, have also been reported. In this article we describe six cases of mostly early-stage hypersensitivity reactions to HD occurring in our department, characterised by malaise, desaturation, bronchospasm and arterial hypotension, with good response to the session's temporary suspension and with reappearance in subsequent sessions that used a synthetic dialyser. No hypersensitivity reactions reappeared in successive observations when the sessions were carried out using a cellulose membrane.

          Specific adsorption of some complement activation proteins to polysulfone dialysis membranes during hemodialysis.

          Dialyser bioincompatibility is an important factor contributing to complications of hemodialysis with well known systemic consequences. Here we studied the local processes that occur on dialysis membranes by eluting proteins adsorbed to the polysulfone dialyser membranes of 5 patients after 3 consecutive routine maintenance hemodialysis sessions. At the end of each procedure, a plasma sample was also collected. These eluates and their accompanying plasma samples were separated by 2-dimensional gel electrophoresis; all proteins that were present in all patients were analyzed by tandem mass spectrometry; and a ratio of the relative spot intensity of the eluate to plasma was calculated. Of 153 proteins detected, 84 were found in all patients, 57 of which were successfully identified by mass spectrometry as 38 components of 23 unique proteins. In 10 spots the relative eluate intensity differed significantly from that in the plasma, implying preferential adsorption. These proteins included ficolin-2, clusterin, complement C3c fragment, and apolipoprotein A1. Our finding of a selective binding of ficolin-2 to polysulfone membranes suggests a possible role of the lectin complement pathway in blood-dialyser interactions.

            Proteomic profiling of blood-dialyzer interactome reveals involvement of lectin complement pathway in hemodialysis-induced inflammatory response.

            dialysis-induced inflammatory response including leukocyte and complement activation is considered a significant cofactor of chronic morbidity in long-term hemodialysis (HD) patients. The aim of this study was to provide better insight into its molecular background.

              Proteomic investigations on the effect of different membrane materials on blood protein adsorption during haemodialysis.

              During haemodialysis procedure, the contact of blood with the membrane material contained in the hemodialyser results in protein deposition and adsorption, and surface-adsorbed proteins may trigger a variety of biological pathways with potential pathophysiologic consequences. The present work was undertaken to examine for protein adsorption capacity of two membranes used for clinical haemodialysis, namely cellulose triacetate (a derivatized cellulosic membrane) and the synthetic polymer polysulfone-based helixone.
